POV pendant

pov

Reader [Franz Gabel] purchased a POV kit from ladyada and started modifying it for his own application. He assembled the POV without a PCB so it could fit inside a small metal pipe and attached a leather lanyard. He’s still in the early stages of the project. It is fully assembled, but he’s working on additions like a docking station to recharge and download new messages. He’s also developed a Flash based system for generating new .c files based on text input. Here is his forum post about his project (Coral CDN, so ladyada doesn’t break my arm).

    super cool have seen alot of these pov projects popping up

    Very interesting!

    Reminds me of my rotating display:

    That’s freakin’ awesome. If you could buy one premade with a dock for recharging and changing the text I’d definitely get one because I lack the skills to build one.

    Would be really good for night clubs etc.

    that’s awesome.
    Reminds of a project in university where I had to get a single line of leds to display an image and then take a photo of the image by increasing the exposure time of the camera and sweeping across the field of view.
    I really wanna try this.

    I know that there are many pov-projects going on and I do not claim the invention of “persistence of vision” for me. Not at least I posted the project in ladyadas forum so everybody can see where I got the basicstarttechnics from.

    The difference to the other projects is the wish to make it availabel for the people that are not able or willing to solder / program and to give it a special use (communicating with unknown people). This will be clear in V.2 with usb- dockingstation to reload the built in li-ion battery and write txt on it very easy.

    tink the magic words are: usability, fun and benefit to use for everybody!

    Posting #5 has a link to a keychain POV that you can spin to create messages in the air. They used an accelerometer to detect the velocity changes and thusly the resultant current velocity. This seems like overkill as increasing spin velocity could stretch a leaf spring. The springs end position could be detected with a variety of cheap methods (capacitance, light reflectivity, magnetic field) to determine velocity.
